L5" upright position for subsequent handling vor delivery to a conveyor.

The object of the invention is to provide a lnovel. can-turningmechanism embodyingv aV pair of interacting can-carrying elements -10whereby the can is turned over with a minimum amount of shock anddangerof denting thereby prevented. More particularly, in accordance with thepresent invention the washed and dried can is delivered to a twopartcarrier whichmoves as a unit vto a partially inverted position andthereafter one of these carrier members is moved relative to the otherto bring'the can to an upright position.

The invention further consists in the several features hereinaftersetforth' andmore.

particularly defined by claims at thelconclusion hereof. p .a f y p .I

Referring tothe drawings Fig. 1 is a. vertical sectional viewv ofthedelivery end of a Fig. 5 is a detaill sectional view, taken on f theline 5-5 of Fig. 13;

Fig. Gris a detail View of one Yof the operating cams.

Referring particularly to Fig. 1,- I have shown the cans 8 and coversQbeing moved machine by intermittent delivery mechanism, which may be ofany suit-able construction, timed to operate in proper synchronism withthe can-turning mechanism Y As herein shown the cans 8 ride on rails orguides 11 and thecovers 9 on a lower guide 12 and between the upperguides 13. For advancing the cans progressively along the guides Vfeedbars 14, mounted on rollers '14 working Von supports 15', are arrangedon either side of the machine and provided with a side elevation of thedelivery `end `end elevation view of thel pivoted ngers 15, held in anupright,fcan engaging position, by gravity, to movey the can forward onthe forward movement ofthe bars 14 but movable beneath the lcan on thereverse stroke to take up a position for forward feed of the neXt can,each bar 14 being operatively connected by a link 16 with the free endof a lever 17 'mounted on a shaft 18 and carrying a roller 19intermediate itsV ends operating in a grooved cam 2O mounted on thedriven shaft 21. For advancing the covers, a reciprocating feed-bar22,.carrying v eratively connected by a link 24with one arm of a lbellcrank'lever 25 pivoted intermediate its ends at 26 onfthe machine frameand having its other arm operativelyconnected `by a link 27 to a crankarm 28 secured tozthe shaft 18 and actuated thereby.y Y

Y The shaft 18 is driven through suitable reduction gearing in ahousing29 from a'transmission shaft 30 connected by a pulley 31 and belt 32 toa pulley l33 on the shaft 34 ofan electric motor V35 or other suitableprime mover. A L j Therrdelivery mechanismy above described for thecovers advances them through the drier and the guides for said coversare then inclined, as shown in Figs. 1 and 2, so that the covers` aredelivered by gravity from the machine.V

The can-turnlng mechanism embodies a pair of can carrier mem-bers 36 and37 with means for moving the'same together and rela- 'tive to eachother.

. The carrier member 36 is in the general form of 4a semi-rectangularshell'havinga bottom portion38 and carried adjacent ysaid bottom on ashaft 39V pivotally` mounted in the framework of the machine, said shaftbeing given an oscillatorymotion in timed relation with thedelivery'mechanism Vby means of a crank arm 40 secured thereto andoperatively connectedby a link 41 to a cam-operpan fittin within thefirst-described member 36 and pivotally connected by lugs or ears 47 toa shaft 48 carried on ears 49 on the upper end of the carrier 37.

For producing relative movement between the carrier members, the carriermember 37 has anopening '50 in its back through which a projection 51,carrying a roller 52 .and a turning arm 53, works.

As seen in Figs. 1 and 2, the projection 51 is designed to'engage theintermediate portion of the carrier 37 to hold it ina. partly inclinedposition as the carrier 36 moves relative thereto to ahoriZontalposition-.and while the carrier 36 with the can 8 therein isin this i 'osition the .arm 53, having V.the roller 54 hereon.andmountedonthe oscillating shaft 55, is.swungupwardly,.turning the canto an .upright position and depositing it on a section-56 of asuitablesupport or `gravity conveyor. The `shaft carries acrank 55 op-;eratively Aconnectedby a link 57 with vacam- .operated Vlever-58pivoted at 59 "at 'one rend and carryingairoller 60 working in agroovedcam'l .mountedron the shaft 21, as 'shown Amore in detail in nFig. 6.

Referringmore particularly to F ig. 1, as thecans 8 are advancedstep'by. step through 'lthewashing machine "theyare tippedoff the 'endof the-guide rails 11 onto the carriers 36 and 37, .then in 'theinclined position Vshown .in dotted'lines and designated by A, in whichposition the carrier 37 rests withinthe shell ofthecarrier 36 andthehead ofthe can rests on the ybottom portion 38 of saidcarrier 36.Thereafterthe turning of the shaft 39 counter-clockwise swings thecarrieri36 from this 'dotted line position to the horizontal positionshown in full lines. As said carrier-member '36 moves to this-positionthe carrier member 37 strikes the projection 51 whichfarrests its andthe cans7 'downward swinging movenient with the carrier 36 and produces"a relative upward swinging movement of said carrier 37 and can 8 aboutEthe :shaft55 as a.center,'as showm in thefdotted line position B, thccan under theseconditions abutting at itsbottom'en'd on one of the.rollers of the support or conveyor 56. As the parts assume thisposition the arm 53 swings the carrier 37 from'the inclinedposiition ABupwardlylto thefull'line position and thus swings the can 8 aboutlitslbottom `into upright position `on the conveyor 56 for removal fromtheimachine.

.Thereafteniaslthe arm 53 swings back, the carrier 37 is moved .back toits intermediate 'position B by aspring 62 acting on a rod 63 .pivotallyconnected to a c'rankfarm 64 on the shaft 55,.'said vspring beingmounted on said rod between'a stop-'nut 65 and a guide bracket 66. The.carrier 37 is then picked up by the carrier 36 on .its .return movementtocanreceiving Yposition andthe cycle of'operation ..is1.'eady tolbe'repeated on the next can.

As the can is always supported by the carrier during the turningmovement and the distances it is moved during its transference to andfrom the turning mechanism are not great, the danger of denting the canis elim- I desire it to be understood that this invention is not to belimited to any particular form or arrangement of parts except insofar assuch limitations are included in the'claims.

What I claim as my invention is 1. In acan-turning mechanism, thecombination of a pair of can carrier members .movable together 'andrelative to each other,

said carrier members being positioned togeth- -er to receive a can ininverted position, means riers being .positioned together to receive acan in inverted position, means for swinging both carrier memberstogether toward Va hori- Zontal position to partially turn the can, and

Afirst carrier and inovable-therewith, said carl"A means forswinging'said second carrier rela379 tiveto .the `iirst carrier to raiseand turn the Acan to complete the can-turning operation.

3. Ifn a cansturning mechanism, the combination of a pivotally mountedcan carrierL a secondcarrier pivotally mounted on the` iirst carrierandnestable within .the same, said carriers .being in nested relation tore- V'ceive 'a can in'inverted position,.means for turning thefirst-named carrier and thereby 'moveboth carriers toward a horizontalposi- Ytion together to partially turn the can. and

means for swinging said second carrier. about its pivot on the firstvcarri er to raise Vand turn the can to complete the can-turningoperation.

4. In a can-turning mechanism, the com? bination with a can-receivingsupport, of a pair of can carrier members movable together and relativeto each other, said carrier members being positioned together to receivea.,

Ycan ininverted position, means for moving" both carriermembers togetherto partially turn the can and bring,r its bottom in abutting relation tosaid support, and means for moving one of the can-carrier membersrelative .to the other to raise and turn the can into upright positionon said support.

5. In a can-turning mechanism, the combination of a can carrierpivotally supported at one end, a second carrier pivotally con! f nectedto the other end of the iirst carrier and .movable with and relativethereto, said carriers being in nested relation to receive a can ininverted position, means for swinging both :carriers about the pivotalaXis of the `iirstL carrier to partially turn the can, means forarresting the swinging movement of the second carrier with the firstcarrier when the can is partially turned, means for thereafter turningthe second carrier on its pivot to complete the turning of the can toupright position, and a support to receive the can in upright position.y

6. In a can-turning mechanism, the combination of a can carrierpivotally supported at one end, a second carrier pivotally connect` edto the other end of the first carrier and movable therewith and relativethereto, said carrier being in nested relation to receive a can ininverted position, means for swinging both carriers about the pivotalaxis of the first carrier to partially turn the can, stop means forarresting the swinging movement of the second carrier with the firstcarrier when the can is partially turned, a support adjacent which thebottom of the can is disposed when partially turned, and means forswinging the second carrier about its pivot to turn the can about saidsupport into upright position thereon.

ln testimony whereof, I affix my signature.
